I think that the general advice is to not bother to try this. Instead work
from an ess-mode edit buffer (*.R) and send commands to the R process from
there using the ess-eval-* commands. (If you do not know these, check the
ESS menu or type 'C-h f ess-eval-<TAB> and a buffer listing them all will
Save the buffer when you quit. When you restart later
M-x find-file whatever.R
will run ess-load-file and you can continue.
Every so often, I forget this advice and enter commands at the R prompt.
If I want to save this work, I can save it as *.Rt, then clean the
transcript, and copy it into or save it as *.R. :-) If you insist on
working from the transcript buffer, you can then kill the cleaned buffer
without saving and redo find-file, and you are ready to go.

I'd start by looking at
I know there are some devotees of 'icicles' on this list, and 'doremi' and
some other links might warrant a look.
